To all whom it may concern:

Be it known that we, FRANK HAYDEN and SAMUEL J. BELL, citizens of theUnited States, residing at Otsego, in the countyof Muskingum and Stateof 01110, have mvented certain new and useful Improve-- ments inMeasurlng-lliachines, of which the cable paid out so that suchmeasurement can be ascertained by a glance at the apparatus.

A preferred and practical embodiment of the invention is'shown in theaccompanying drawings, wherein Figure 1 is a View in front elevation ofthe measuring apparatus as it appears when in use. Fig. 2 is afragmentary view in rear elevation of the measuring apparatus. Fig. 3 isa similar view, the tally wheel and the cable pulleys being omitted.Fig. 4 is a vertical longitudinal sectional view taken on the line 4-4,Fig. 2. Fig. 5 is a detail view ofthe rear surface of the supportingboard showing a pawl and ratchet for the shaft of the tally wheel. Fig.6 is a detail perspective view of the pawl shown in Fig. 5.

The improved measuring apparatus comprises a frame 7, arranged in theform of a vertical derrick adapted to be placed across the upper end ofa well 8 and which carries a vertically arranged supporting board 7through which stub shafts 9 and 10 project laterally, and on which idlerpulleys 11 and 12 are mounted. Pulleys 11 and 12 are in spaced verticalalinement. Said pulleys are preferably grooved peripherally and may besolid, as shown or of any other suitable or preferred type. 'A driveshaft 13 has a projecting end 14 that is centrally disposed and to oneside relatively to pulleys 11 and 12 and on which a guiding pulley 15 ismounted. A'windlass 16 is disposed adjacent one end of derrick 7 and acable 17 extends therefrom and passes around a pulley 17 in the upperportion of said derrick. Cable 1.7 depends from pulley 17 and engagesone portion of pulley 11, the portion of pulley 15 that. projectsbetween pulleys 11 and 12, and one portion ofpulley 12. This arrangementof pulleys 11 and 12 places a tension on cable 17 and "holds the same-1ncontact with pulley 15. The free end of cable 17 carries a'hook 18 forengaging a loop 19 carried by a weight 20. Shaft 13 extends transverselyacross and is journaled in a bearing 21 carried by the board 13* thatprojects at right angles from one longitudinal edge of board 7*, saidshaft being provided with threads 23. A dial wheel 24 is rotatablymounted on ashaft 25 projecting from board'13, said wheel having itsperiphery provided 'with teeth 26 that are in mesh with the threads ofshaft 13. The outer surface of dial 24 is provided with graduatio-nsdesignating feet and fractions thereof, and said outer surface is alsoprovided with an upstanding lug 27 Board or support 13 carriesa bearingblock 28 in which a shaft 29 is journaled.

The outer end of shaft 29 has a tally wheel said board. The free end ofpawl 33 has an Y angular tooth 37 that engages the teeth of ratchet 32and opposes rotary movement of said ratchet. An indicator or pointer 38is fast on block 28 and overlaps dial 24.

The threaded engagement of shaft 13 with dial 24 issuch that onecomplete rotation of said dial designates 500 feet and the arms 31 oftally wheel 30 are marked to indicate measurements in 500 feet. Forexample one arm is marked 000, the next arm 500, the next one 1,000, andso on, and as the said arms'are in the path of movement of lug 27, itwill be seen that the first rotation of dial 24 causes lug 27 to movethe zero arm and bring the 500 feet arm in'position to be eneration byindicating the measurements at any point bet-ween two of the arms 31.

In the foregoing description it has been stated that the tally arms 31are marked "to indicate measurements of 500 feet and over, this markingbeing adapted for deep wells, such as oil wells, but it will beunderstood that different markings can be used if desired so that thedepth of shallow wells can be readily ascertained.

In addition to the foregoing prominent feature incidental details suchas spacing sleeves, or ferrules-39 are employed for the shafts 9, 10 andlet to space the pulleys 11, 12 and 15 from board 7, and a similarsleeve or ferrule 40 is carried byshaft to space the dial 24 from board13. The frame, in-

, cluding the boards 7 and 13 is preferably .of metal, although it willbe clear that wood or other material may be used if desired. hat weclaim as our'invention is A measuring apparatus comprising amain frameadapted 'to straddle the mouth of a Well, a vertical supporting board onsaid frame, lateral stub shafts on said board,

spaced idle pulleys on said shafts, a' threaded drive shaft, a drivepulley thereon partly between and in the same vertical plane with thesaid idle pulleys, a Windlass operated cable passing over an elevatedpulley and downward between said idle pulleys and said adapted to .passover said pulley, an indicator carried' by said support and cooperatingwith said tally wheel, and means for retarding the rotary movement ofsaid wheel.

In testimony whereof we hereunto afiix our signatures in presence of twowitnesses.
